Introduction to ADSS Suspension Clamps
In overhead fiber optic cable systems, the ADSS suspension clamp plays a crucial role in ensuring the safe and stable installation of ADSS cables (All-Dielectric Self-Supporting cables).
An ADSS cable clamp is specifically designed to support and suspend fiber optic cables on poles or towers while minimizing mechanical stress on the cable jacket. By using a preformed suspension structure, the clamp distributes pressure evenly along the cable surface, reducing the risk of deformation, vibration fatigue, and long-term damage.
Compared with traditional suspension hardware, preformed ADSS suspension clamps offer several advantages:
Even stress distribution on the cable
Quick and tool-free installation.
Strong resistance to environmental corrosion.
Reduced cable vibration and fatigue
Extended service life of fiber optic lines.
At Vilun Electric Co., Ltd., we specialize in the manufacturing of preformed line products and ADSS cable fittings. With more than 20 years of industry experience and exports to over 100 countries, our products are widely used in power transmission lines, telecommunication networks, and fiber infrastructure projects worldwide.
This guide explains the structure, materials, and installation steps of an ADSS suspension clamp to help installers perform a safe and standard installation.
Components of an ADSS Suspension Clamp
1. Rubber Clamp Insert
The rubber clamp insert is made of high-quality rubber combined with a reinforced center structure.Key features include:
Excellent ozone resistance.
Chemical resistance.
Weather and aging resistance.
Stable performance in high and low temperatures.
High elasticity with low compression deformation.
This component protects the ADSS cable jacket from mechanical damage.
2. Aluminum Clamp Housing
The aluminum clamp housing is manufactured using corrosion-resistant aluminum alloy die casting.Advantages include:
Excellent atmospheric corrosion resistance.
Stable chemical properties.
High mechanical strength.
Long service life in outdoor environments.
3. Inner Preformed Armor Rods
The armor rods are made from high-strength aluminum alloy wire with carefully controlled mechanical properties.Their functions include:
Increasing contact area between clamp and cable.
Reducing local stress concentration.
Protecting the cable from abrasion.
Improving vibration resistance.
4. Outer Preformed Rods
The outer preformed rods use the same high-strength aluminum alloy material as the inner rods and provide additional mechanical support and stability.
ADSS Suspension Clamp Installation Steps
Step 1 – Mark the Cable Position
Use a thin tape or marker to mark the center of the suspension point on the ADSS cable.
Step 2 – Install Inner Armor Rod Subsets
Group the preformed rods into bundles of 2–3 rods and align the center mark of the rods with the mark on the cable.
Wrap the rods around the cable 3–4 turns.
Step 3 – Install Remaining Armor Rods
Repeat the process until all armor rod subsets are installed, ensuring the center color marks align.
Step 4 – Complete Wrapping by Hand
Wrap both ends of the rods by hand only.
Do not use tools to avoid damaging the cable jacket.
Step 5 – Install Rubber Clamp Insert
Place the rubber clamp insert over the preformed rods and secure it temporarily with tape.
Step 6 – Install Outer Preformed Rods
Align the center marks of the outer rods with the center of the rubber insert.
Ensure the rods follow the curvature of the rubber clamp surface and wrap them 2–3 turns on each side.
Step 7 – Install Remaining Outer Rods
Install the rest of the rods evenly along the rubber insert.
Ensure:
No crossing rods
Even spacing between rods
Step 8 – Finish Wrapping
Wrap both ends of the rods naturally by hand.
Do not use tools.
Step 9 – Install Aluminum Clamp Housing
Position the aluminum clamp plates outside the outer rods with the hanging ear facing upward.
Step 10 – Secure Bolts and Cotter Pins
Tighten the nuts and install the cotter pins to secure the structure.
Step 11 – Attach the U-Shackle
Fix the U-shackle to the tower or pole hardware.
Step 12 – Final Tightening
Tighten the nuts and install the cotter pin securely.
Step 13 – Installation Completed
After confirming all components are properly installed, the ADSS suspension clamp installation is complete.
Installation Tips for ADSS Cable Clamps
To ensure long-term reliability, follow these installation tips:
Always install preformed rods by hand.
Avoid scratching or damaging the cable jacket.
Ensure even spacing between rods.
Confirm the clamp is centered at the suspension point
Double-check bolts, nuts, and cotter pins after installation.
Proper installation significantly improves the service life of both the ADSS cable and suspension hardware.

FAQ – ADSS Suspension Clamp
What is an ADSS suspension clamp used for?
An ADSS suspension clamp is used to support and suspend ADSS fiber optic cables on poles or towers while protecting the cable from mechanical stress and environmental damage.
What is the difference between an ADSS suspension clamp and a tension clamp?
A suspension clamp is used at straight sections or small angle towers to support the cable, while a tension clamp is used at dead-end or angle towers to withstand higher tensile loads.
Can ADSS suspension clamps be installed without tools?
Yes. Most preformed ADSS cable clamps are designed for tool-free installation, which prevents damage to the cable jacket.
How long does an ADSS suspension clamp last?
High-quality clamps made from aluminum alloy and corrosion-resistant materials can typically last 20–30 years in outdoor environments.
